PHOTOGRAPH -BURNlSl-IER.

SPECIFICATION forming part of Letters Patent No. 355,399. dated January' 18, 1887.

Application filed April l2, 1886.

To all when?, t may concern:

Be it known that l., VARREN H. BOLES, a citizen of the United States, residing at Syracuse, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in Ihotograph-Burnishers, ofwhich the following is a full, clear, and exact description.

This invention relates to machines for burnishing photographs, and has for its object to economize the first cost of manufacture, gain time in heating the burnishing-tool, and save cost and labor in heating, make a durable and easily-adj usted machine and one having readily-removable parts, avoid collection of soot, and generally to remove ol'ijectionable features I meet with in such machines as have come under my notice in a long practical experience in the use and sale of this class of goods.

The invention consists in a tubular or flue burnishing-tool heated by a kerosene or other cheap burning-fluid lamp or gas, means for adjusting and removing such tool, means for ascertaining and thereby regulating its teinperature, means for readily applying and removing the heater, and also a tubnlar'ventilated feed-roll, all ,and severally as I will now proceed to particularly set forth and claim.

In the accompanying drawings, in the several figures of which like parts are similarly designated, Figure lis a front elevation of one form of 'my machine; Fig. 2, a top view. Fig. 3 is a bottom view of the burnishing-tool detached. Fig. 4 isavertical section in the plane of line :v x, Fig. l, with the lamp removed, and Fig. 5 a vertical section on a larger scale in the plane of line y y, Fig. l.

The frame may consistvof two upright castings, a a, connected and braced by a table, b, detachably bolted thereto, as indicated in Fig. 4. The upper ends of these uprights are provided with housings c c for the journals of the feed-roll d, and this feed-roll I make hollow,so as to ventilate it and prevent .condensation of vapors thereon, thus avoiding spoiling' the picture or rusting the polishing-tool. The surface of this feed-roll may be roughened or milled by means of a knurling-tool in a lathe to give it the necessary bite or friction upon the picture to advance it regularly and uniformly over the burnishing-tool.

end, which have tapped seais i, which rest upon pivot or fulcrum screws j, arranged in screw threaded lugs 7c on the uprights a a. rIhese screws, by vertical adjustment in the lugs, admit of the raising or lowering of the burnishing-tool with respect to the feed-roll, and said screws may be set in such adjustment by the lock-nuts Z.

The arms are connected by a rod, m, to prevent iheir warping out of alignment with the screws. On the opposite side ofthe burnishing-tool a central arm, n, projects out over the table b and is provided with a temper-screw, o, whereby the requisite pressure may be given to the picture, said screw bearing or seating on the table to this end, and its rotation in the arm n serving to move the burnishing-tool as a lever upon its pivotscrews. This construction enables me to gain complete and instant control of the pressure upon the picture. Obviously by lowering the arm n on its screw o the tool f may be readily removed from the machine for repair or cleaning or replacement.

Damage to and loss of pictures are of quite frequent occurrence in burnishers now commonly used, owing to the lack of provision for ascertaining and regulatingthe heat. In my invention the burnishing-tool is made hollow and open from end to end, holes p being made in the uprights in alignment with the tool, so as to obtain a through-and-through passage. An opening, q, is made in the lower part of the tool, about midway of its length, and this opening has at one side a stationary fender, r, and at the other a hinged fender or hood, s, and in this opening and between these fenders is received the chimney t of an ordinary coaloil or other burning-duid lamp,u. .The hinged fender permits the ready insertion and removal of the lamp or heater. The burnishing-tool being hollow and open from end to end, a natural draft'will be had through it, and combustion will be stimulated and the rapid heating ofthe tool insured. A thermometer, o, is applied to the burnishcr, in order to enable IOO the operator to ascertain and regulate the ternperature of the burnisher. The wick of the lamp will be raised and lowered to increase or diminish the volume of ilame and heat, according to the indications ofthe thermometer.

Some ofthe advantages of my invention are as follows:

First. There is neverany possible danger of the picture being spoiled by the smoke coming in contact with the face of the same, as the smoke emerges within the tine and is carried off at the ends ofthe same bythe draft.

Second. Theaccumulation of soot under the burnishingtool is avoided by the draft through the iiue, which carries off all the smoke, and thus saves the necessity of using the fuel to heat the soot over and over again, as is the case with all bnrnishers having` no draft.

Third. The tension is even and invariable, absolutely positive and alike on both ends. and gained by leverage from one point, and hence there is no possibility of the picture running crooked or being twisted.

Fourth. The heat can be graduated at coinmand by simply raising or lowering the wick of the lamp, and can be accurately gaged by the thermometer. Consequently the chance of blistering or diseoloring by getting the burnishing-tool too hot is avoided.

Fifth. My machine will burnish the cards equally as well on the edges as in the center, as the heat is uniformly distributed by the drafts created by the fines under the burnishing-tool drawing the heat uniformly from end to end of the tool.

Sixth. The burnishing-tool can be cooled much more rapidly than any other, as it is only a hollow tube of metal, instead of asolid block of iron; hence, if it is necessary to remove the burnishingtool, to remove a scratch from the face of the same, it can be readily done without danger of burning.

Seventh. The thermometer attached to the side of the flue will tell precisely what degree of'heat the burnishiugtool has attained. Consequently ene is not compelled to remain in doubt, and thus saves the necessity of defacing two or three pictures before ascertaining whether the burnishing-tool is in proper condition for work.

Eighth. There is no possibility of any moisture forming or condensing on the feedroll or polishing-tool during the process of heating, because the feed-roll is made hollow its whole length, thereby creating an airchamber through the center of the same from end to end. This positively avoids the serious danger of spoiling the polishing-tool or pictures by contact with such moisture.

Prior to my invention it has been customary to roughen the surface of feed or pressure :rollers by longitudinally serrating them by draw-filing; but this is an expensive operation.' I accomplish this roughening in a better and far more expeditious manner by the use of a knurling-tool in a lathe.

IVhat I claim is- 1. In a photograph burnisher, a tubular burnishing or polishing tool open from end to end and having an opening to receivethe chimney of the heating-lamp and a hinged fender or hood to permit ingress and egress of the lamp, combined with such lamp, substantially as described.

2. In a photograph burnisher, a tubular burnishing or polishing tool open from end to end and having an openingr to receive the chimney of the heating-lamp, and a hinged fender or hood to permit ingress and egress of the lamp, and a stationary fender co-operating with the hinged fender to inclose the upper end or outlet of the lamp-chimney, combined with such lamp, substantially as described.

3. In aphotograph-burnisher, aburuishingtool provided with fulcral arms and adjusta- 'ble pivot or fulcrum screws, on which said arms rest, and an intermediate temper-screw, substantially as described.

4. In a photograph-burnisher, the burnishing or polishing tool and a heater therefor, combined with a temperature-indicating device, such as a thermometer7 substantially as described.

5. In a photographburnisher, the tubular feed-roll d, open from end to end to ventilate the same, combined with a burnishing-tool and means to heat the latter, substantially as described.

6. The feed-roll of a burnishing-machine the acting or feeding surface of which is knurled as distinguished from draw-tiled, substantially as described.

In testimony whereof I have hereunto set my hand this 10th day of April, A. D. 1886.
